The Schedule refen'ed to in these Letters Patent and making part of the name.

My invention consists of a creeper, constructed in the w peculiar maner fully vdescribed hereafter, for ready and tirm attachment to, and as ready displacement from the sole of a boot or shoe.

In order to enable others to make and use my'invention, I will now proceed to' describe the mode of construoting and applying the same, reference being had to the accompanying drawing, which forms a part of this specification, and in which- Figm'e 1 .is a seotional view of my improved creeper,

attached to the sole of a boot;

Fignre 2, a' perspectiverview; Figure 3, an inverted lplan view; and

Figure 4, a sectional view, showing the creeper (letaohed from the' boot. I

Similar letters refer to similar parts throughout the several views.

A and A' are two plates, connected together by a strip, B, of rubber or elastic fabric.

The under side of the portion a of leach plate is ronghened, and between the rough surface and a' metal strip, b, (the latter being also roughene'd,) is secured the elastie strip B, by rivets, the heads of which are so 'pointed as to form the spikes of the creeper. I

The metal strips b are of suchalength that the strip of one plate *shall nnderlap that of the other plate when the creeper is adjusted to the boot, as shown in fig. 1.

On the upper' edge of theportion e of each plate are two projeotions, those of one plate for fitting over one edge of the sole, and those of the other plate for fitting over the opposite edge of the sole.

. In adjusting the creeper to its place, the lips f f of one of the plates are hooked over one edge of the sole, and then the other plate, after' stretching 'the elastic strip, is adju'sted with its lips to overlap the opposite edge of the sole. i v

; On placing the foot on the ground, and bearing with the weight of the 'body on the creeper, the projections on the portions a, of the plates will penetrate the sole of the boot, and thus prevent all tendenoy of the'creeper to slip longitudinally,while the tendency of the stretched strip B to rccoil causes the creeper to maintain its hold of the sole laterally with a sutfioiently firm gripe to pre' vent displacement.

The metal strips b, ,while serving to aid in securing the elastic strip, proteot the latter from being unduly wo'rn or injured' by rough roads.

The creeper, as will be evident, can be readily detached 'when necessary, and folded' in a small compass.

I elaiml as my invention, and desire to secure by Letters Patent- 1. Spiked plates A and A', adapted to the edge of the sole, and connected together by an elastic strip, all substantially as and for the lpurpose herein set forth.

v2. The metal strips b b, connected to the plates A i A', and overlapping below the rnbber strip B, as specified.

In testimony'whereof, I have signed my name to this specification, in the presence of two subscribing witne'sses.
